Eastern Shore of MD | Our main supplier is set up to melt K into either suspensions or clears and that is what we usually apply preplant. IIRC the max K in a clear is either an 0-0-10 or 0-0-12, above that it needs to be a suspension- I would think any of those would be way to hot to apply foliar. Are you fertigating? Last year we fertigated something like a 15-0-5-6S - not sure if that was the exact analysis but it was a clear and that is close to the analysis we used. Probably will drop the K out this year and just run a NS as I think,for us, those nutrients are making giving us the most improvement. We are on sand, CEC 3-5. | |
